本文详细介绍了在Freemarker模板中遍历Map和List对象的方法，特别强调了Map对象中Key的定义及获取方式，并通过实例展示了如何在网页布局中灵活运用这些知识。

freemarker遍历map对象实例，这个与遍历list对象有点不同。当Map里面的key 是Object(String,Integer,etc）等要通过以下的方式来得到。

code<#list testMap?keys as testKey>

       < option value="${testKey}" >

              ${testMap.get(testKey)}
 
     </option>
</#list>

code
1 2 3 4 5 6	`<#list testMap?keys as testKey>` `<` `option` `value="${testKey}"` `>` `${testMap.get(testKey)}` `</option>` `</#list>`

或者使用：

code<#list testMap.keySet() as testKey>

       < option value="${testKey}" >

        ${testMap.get(testKey)}
 
     </option>
</#list>

code
1 2 3 4 5 6	`<#list testMap.keySet() as testKey>` `<` `option` `value="${testKey}"` `>` `${testMap.get(testKey)}` `</option>` `</#list>`

切记在webwork自带的freemarker中对Map中Key的定义为String类型(如果你想用${Map[key]}这样取值的话;如果用${Map.get(key}这样取值就可以用其他类型，如Map<Long,Object>),更高片本是否可以用其他类型本人未曾验证。

code<#list pager.map.get("m") as list>

                        <li<#if (list_index + 1) % 4 == 0> class="end"</#if>>

                            <a href="${base}${list.htmlFilePath}" class="productImage" target="_blank">

                                <img src="${base}${(list.productImageList[0].thumbnailProductImagePath)!systemConfig.defaultThumbnailProductImagePath}" alt="${list.name}" />

                            </a>

                            <div class="productTitle">

                                <#if (list.name?length < 28)>

                                    <a href="${base}${list.htmlFilePath}" alt="${list.name}" target="_blank">${list.name}</a>

                                <#else>

                                    <a href="${base}${list.htmlFilePath}" alt="${list.name}" target="_blank">${list.name[0..25]}...</a>

                                </#if>

                            </div>

                            <div class="productBottom">

                                <div class="productPrice">

                                    <span class="price">${list.price?string(priceCurrencyFormat)}</span>

                                    <span class="marketPrice">${list.marketPrice?string(priceCurrencyFormat)}</span>

                                </div>

                                <div class="productButton">

                                    <input type="button" name="addCartItemButton" class="addCartItemButton addCartItem {id: '${list.id}'}" <#if list.isOutOfStock>value="缺货" disabled<#else>value="购买"</#if> hidefocus="true" />

                                    <input type="button" name="addFavoriteButton" class="addFavoriteButton addFavorite {id: '${list.id}'}" value="收藏" hidefocus="true" />

                                </div>

                            </div>

                        </li>

                    </#list>
